Restauration de la flore des prés salés continentaux : expérimentation sur le marais de Saint-Beauzire (Puy-de-Dôme, 63)

Abstract : This article presents a case study of recolonization by flora constituting a continental salt meadow type vegetation after the removal of an embankment on a continental salt marsh in the Limagne plain (Puy-de-Dôme, France). Salt marshes indicator plants was monitored in presence/absence in a network of 104 meshes of 10 m². We were able to show the rapid and lasting colonization of Puc-cinellia distans and Juncus gerardi, but also the slower and variable installation of Spergula media and Plantago maritima. We mapped spatial and temporal evolutions of this colonization for 6 different species. Among the halotolerant species, one should note the increase in the population of endan-gered species such as Inula britannica. The monitoring protocol allows us to conclude on the interest of this type of embankment removal operation to restore the abiotic parameters and the flora of the «continental salt meadow» vegetation.
